- 8. External Interface Support XML Support enables XML–Smalltalk object mapping, includes a server interface via XML request handlers and reading of remote resources B disk via TCP sockets using HTTP requests OLE Support enables an application to use OLE clients and custom control services. Domino Connection allows an application to retrieve and work with Domino documents as well as access Notes mail system.

- 87. Monticello Declarative modeling Distributed repositories Optimistic code merging Vendor round-tripping
- 88. Monticello ☹ Slow with large repositories ☹ Inconvenient with many packages ☹ Awkward when renaming and moving between packages
- 89. Future?
- 90. Metacello Declare and load package configurations Express dependencies on other projects Easily upgrade to newest versions
- 91. Mason Automate build process Run tests for each package + dependencies
- 92. Monticello2 Faster Per-method version history Better interface for projects with many packages Easier to port? (uses Grease)
- 93. book.seaside.st
- 94. Summary Write tests! Avoid extended syntax Use ANSI where possible Package out platform-specific code Slime/Lint for what you can’t use, Grease for what you can
